These extraordinary images show the lengths desperate migrants are willing to go to in order to get into the UK.

Migrants determined to reach the UK have repeatedly targeted freight lorries as a means of crossing the Channel from Calais, France.

It has resulted in some lorry drivers boycotting Calais for fear that they may inadvertently be involved in an accident. In May, lorry driver Michael Pearson said he feared somebody would soon be ‘seriously killed or injured’ in their attempt to enter Britain as stowaways.
